Be it known that I`,WALTE13. G. MAcoMBER, e citizen of the UnitedStates, residin et Johannesburg, 'count1 of Kern, State of eliforniti.,hnve lnvente Ae new and useful' Rotsry Engine or Pump, of which thefollowing is e-specicntion. f I This invention relates lto e rotaryengine or pump invwhich s. cylinder having a. reciprof5 '1cceting'piston isegnployed, and the object of the invention is to employa. lurslity of cylinders with their pistons en cause s rotary bodilymovemen'toiv the c lind'ersin a.` plane l et righ.' 'singles tiithe.ection-of piston ltreve pistons is applied 'to s rotating element whirotetes in e lanest venengle to the rotation of the cylin ers, and efurther object is to equalize theprefssure ofnnefpiston egeinst` seidelement by sn 'o osing rassure roduced by snotlzlerV pistdet the-Ibpposite Islide p of seid clement, thereby avoiding end thrust end.vibration. .In this engine no ily-wheel is required, es the cylinderspartake of bodily vze rotation end their' weight is sufficient. to

ceuse'them to perform the service of a; flywheel. Esch piston, ,in 'thisembodiment, is propelled by t e motive huid, forexam le, steam or sir,inboth directions. In ot er wor-ie, eschpiston is double acting, and a.

. 'further veryl'mportsnt object ci the invenf .tion is to dispense withmovable valves :md their necessary attendent mechanism for operetingthem, such es eccentrics, cams, end

135 the like', lend to `e'ect the admissionv and efxheust of thecylinders by the bodily rotating movement of the cylinders. A

A iur-ther obj'ectis to provide a, manually y controlled valve for;reversing the sequence of 40 edinission. and exhustend thus provide foropereting the engine `in either direction.

From the foregoing it'will be seen that the .engine`= may be ofexceedingly sim le con- .,struction and .that the only .-moveb epsrtsthereof smiths-cylinders,'their pistons, the engulsrlydis osed rotatingelement and the "connections, etween said .elementsnd'the pistons.-

The other end of the cylinder shaft 7 is preferably tapererhssshown, and has a fork 9 through which passes 'e cross rod 10, the crossrcd'10 havin r 'trunnionsA 11 whichpivot the .cross rod tot e fork' 9thereby forming e. universel joint between the cylinder shaft and 'crossrod; The cross rod 10 extends dismetricslly through a hol- -lowhemisphericsl bowlghereincfter termed the inner bowl 12, and pins 13hold the cross rod .10 from slipping endwise in the inner bowl. Theinner bowl 12 is nested within-s similarly shspedouter bowl 14. Theouter -bow1 14 is carried on the end of e sleeve 15 journaled inbearings 6 and the inner bowl 12 1s carried on a shaft 16 which isjournsled 'in sleeve 15, the shaft 16 havin e collar 17 which rbearsagainst the endo sleeve 15 to .prevent relative lon 'tudinel movementbetween the sleeve en shaft.

Morin-ted on the cylinder shaft 7 y and .preti crsbly cast integrally`therewith are four cyl- ,'inders 18, 19, 2() and 21, esch cylinderhaving la removable head 22. Mounted to reciproeste within therespectivecylinders 18, 19, 20and 21 'are pistons 18, 19, 20 and 21s,

which Vpistons are provided respectively with pistonrods 18h, 19h, 20band 211?, eech piston lrod passing through aglend 23 in the end of, 'itscylinder.y Thefonr -piston. rode` ell-have forked ends 24 which sllde onweysr pro# `jee-ting from the cylinders, end in. eeich forked."

-the sleeve 25 can swing therein. The ends of cross rod are mounted insleeves 25 of the piston rods 19'D `and 21". Projecting from the outerbowl 14, from diametricallv opposite points, are two trunnions 27, whichtrunnions project into sleeves connected Y Thus,ipistons 18a and 20'-are connected with the outer bowl 14 and the pistons 19 and 21 u areconnected with theI inner bowl 12.

The cross rod 10 which is carried by the inner bowl 12 is free-trom engarement with the outer bowl 14 and lies at rig it angles to the trunnions27 of the outer bowl, but this relative angular position is not'maintained absolutely, 4for as will b'e hereinafter pointed out, thereis a slight relative movement bctween bowls 12 and 14 which causs acertain amount of change in the relative angular po sitions of cross rodk1.0 and trunnions 27. However, at' all times the cross rod 10 may besaid to be substantially at right angles with the trunnions 27, as therelative movement ,with respect thereto is slight. The cylinder' '18 isprovided at each end, respectively, with port 18 and 18d; cylinder 19 isrovided with similar ports19 and 19"; cy inder 2U withsimilar orts 20?and'20fi; and cylinder vrts 21c and 21d. A passage 28formed 11i-cylindershaft 7 connect" `ports 18" and port 20 d, and a rpassage 29 cone. nectsort'2d with port 18 as-shown by\ dotted) do. not lcoinnmnicatc with eachother. A passagev fconnects port 19 vwith port 21 d, and a passage 31connects port 21c with port 19d as shown by dotted ines, Fig. 2, andthese" latter pass es doy not communicate with-each other. alillecylinder shaft 7 at the .head end is provided with four longitudinalpassages 1186,19", 20a and 21" which respectively communicate with ports18, 19, 20c

which the reversing .t

and 21 c, and the said passages all open atthc concave end 8 of theshaft 7. A reversing valve 32 is arranged at the concave lend of shaft 7and has a rounded nose which fits the concave Aface 8. VThe other end ofthe ref verein valve is formed with a socket providing a c amber 33.Projecting part way into the chamber 33 is a stationary shaft 34 uponvalve 32 is revolubly mounted. The sha 34 is hollow to form an inlet forthe admission of the motive fluid to the chamber 33, and an annulargland 35 is arranged between the reversing valve 32 and shaft 34A toprevent leakage. The reversing valve 32 is provided with passages 36 and37, bothv passages-o ening at the round end of the reversing va ve andthe passage communicating directly with chamber 33, while the passage 37does not communicate with passage 33 'but is open to the atmosphere.

A reversing lever 38 is provided on the reversing valve 32 for operatingthe valve, and stops 39 limit the movement of the reversing linesin'Fig. 3; thel said two passages esami.

'valve to an arc of half a circle. When thc 'to chamber 33 and while mchamber 33 cxerts end pressure against. the reversing valve,

piston 18 is moved to the right und piston 20 moves to tho lci't..During this movement ol the pistons thc motiviv Huid on the right vhandsido of pistou 18 passes out through port 18d und through passage 29 topassage 20e where it mingles with motive iiuid at the left of piston 20,and the combined motive fluid passes along passage 2() into passage 37of the reversing valve and exhausts into theI atmosphere. The combinedpushin f effect of piston rod 18 against the associate trunnion ofluitcr howl 14 and the pulling effect of piston rodv 20" upon itsassociated trunnion of the outer bowl 14 imparts rotation to the outerbowl on account of the'angular thrust and pull of the said two pistonrods on, the bowl which causes the outer bowl to rotate, and as the bowlis thus caused to rotate, it in turn imparts through piston rods 18b and20b rotation to the cylinders, and as all of the cylinders are mountedas one piece they are all caused to revolve together, and for thatreason at lthis trfif.- tl. inner bowl 12 is also given rotation thromhthe' medium of the other air of piston rods connected therewith. Wiienthe piston 18- arrives at port 18d and piston 2Oa arrives at port 20 c,the cylinder shaft 7 has been turned one quarter of arevolution, whichbrings passage'21e into register with inlet passage 36 and brings inletpassage 19 into register with exhaust passage 37, whereupon the pistonin cylinders 21 and |19 are moved in o po- 'tending to hold its roundnose iirmlyseated site directions by thelintroduction an exhaust ofmotive fiuidLthereto in a manner similar to that dcscrib` d inconnection with cylinders 1.8 and 20, and during '-his move ment ofpistons 19b and 2lb a combined push, and pull is exerted through thecross rod 1() upon the inner bowl 12, which in turn transfers rotationto the cylinders 'and to the shaft 16 and sleeve 15 through the secondquarter oi' revolution. Upon the completion of the second quarteror'evolutio'n the passa ye 20 is in register' with inlet passage 36 an(passage 18e is m register with exhaust passage 37, and piston 20'?. ismoved to the right and pistou 18"l moved tothe left, a ain acting upontheouter bowl, and throug i the parte connected therewith impartingrotation as before to the cylinders yand shaft-16 and quarter o-.the ofcylinders' sleeve 15, and during the last revolution pistons 19 and 21*l19 and 20 are acted on in the same manner. It will thus be seen that thefour ports 18, 19e, 20e and 21 e are successively brouglm'lv tocommunication with inlet. passage 36 an in sequence are brou ht intoregister with outlet passage 37. T us, the cylinder shaft l7 in itsrevolution acts as a valve to permitiintake and exhaust according to theposition 'of these four passages.v ating the lever 38, the reversingvalve 32 ma be turned through half a circle which wil bring the exhaustpassage 37 at the top and intake passage 36 at the bottom, and from Fig.3 it will be seen that exhaust passage 37 is then in communication 'withpassage 18", while intake passage 36 is in communication with passagewhereupon motive fluid will be introduced throu h passpge in to assa e20e and throug port U at the le t of cy inder 20, while fiuidwillexhaust from the left side of cylinder 18 through passage 18e to exhaustpassage 37,- luid being admitted to the right of cylinder 18 throughpassage- 29 which communicates with passage 20e.

. This will result inf-imparting reverse movement to the motor.

Acareful consideration ofthe principles of construction "will show thatthe ev of each piston rod has a path of travel rough a circle, viewed ina direction along the stroke of the piston rod, but as the inner andouter bowls are also circular and rotate at an an le the points ofContact of the forked'ends of t e piston rods will vary on the.trunnions as the trunnions move in' anellipse when viewed alon the lineof piston travel. On account of t is the sliding connection between thetrunnions .and iston rod endsk is rovided. From this it wi be seen thata slig t differential movement oecursbetween the two bowls, first onebowl slightly leading and then ,the other leading, accordin to thechanging radius from centers of bow s to the contacte ing points on thetrunnions,and it is thus necessary to provide for a certain amount ofrelative movement between the two bowls'12 and 14, which relativemovement is provided as was before pointed out in the s eciiication.Power can be taken oli' either rom the sleeve 15 or shaft?. i
